Answer:

y=4 , x= 12

Step-by-step explanation:

This question deals with linear equations so, with this problem, subsitution is the easiest form of solving.

x + y = 16

8 + y = x

Now you know that x = 8 + y, so replace it in the opposing equation.

8 + y + y = 16 (simplfy)

8 + 2y = 16  (subtract  8 from each side)

2y = 8 (divide each side by 2)

y = 4

plug into other formula

8 + 4 = x

x =12

Find the slope of the line that passes through the points (0, -3) and (-4,1).
kozerog [31]

The formula for slope is \frac{y_{2} -y_{1} }{x_{2} -x_{1} }

In this case:

y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0

so...

\frac{1 - (-3)}{-4 - 0}

\frac{4}{-4}

-1 <<<The slope

Hope this helped!
